Description

The present invention relates to an information processing apparatus and an information processing method, for example, an information processing apparatus related to selection of a broadcast time zone.

In commercial broadcasting, which does not collect reception fees from viewers, the main source of revenue is the consideration for the broadcasting service of advertising broadcasting (CM: Commercial Message, Commercial Advertisement). Broadcasters may recruit advertisers (sponsors) for each broadcast time zone when commercials are broadcast. The broadcast time zone of the CM is called an advertising space or a CM space. CMs are roughly divided into "time CMs" and "spot CMs". The time CM refers to a commercial in which the advertiser provides the main program and broadcasts within the CM frame included in the broadcast time of the program. The main program refers to a program whose main purpose is not to promote products or services, such as news, dramas, quizzes, and competitions. The spot CM refers to a CM that is broadcast within a predetermined advertising space by a broadcaster. However, even the advertising space of the spot CM is often associated with a specific main program. In the business model of broadcasters, time CM has been the mainstream in the past, but nowadays spot CM has begun to spread.

On the other hand, the effect of the CM (advertising effect) is emphasized by the advertiser, and it is expected that it will be viewed by a larger number of viewers. In the spot CM, the advertiser can specify a desired date and time and have his / her own CM broadcast. In order to take advantage of this, advertisers can use multiple ad slots at once to appeal to a wide range of viewers about the products and services to be advertised, and to promote intensively within a predetermined period. Become.
On the other hand, broadcasters usually set the price so that the higher the advertising space is, the higher the advertising space is expected to be in order to secure profits.

Under such circumstances, a method for selecting various advertising spaces has been proposed. For example, Patent Document 1 discloses an ad space optimization system that predicts the audience rating of an advertisement by a viewer and optimizes the advertisement in a broadcasting medium. Patent Document 2 discloses an ad space selection system that selects a desired ad space from a plurality of ad space based on the acquisition cost of the ad space and the contact probability of the ad space.

However, devices that receive advertising broadcasts may overlap between a plurality of advertising slots. Therefore, even if an advertiser broadcasts an advertisement using a plurality of ad slots, it is not always received over a wide range of devices. On the other hand, advertisers usually have budgetary constraints.

Aspects of the present invention have been made in view of the above points, and it is an object of the present invention to more accurately evaluate the range of devices expected to be received and select an advertising space under predetermined application conditions. Make it one.

The present invention has been made to solve the above problems, and one aspect of the present invention is at least the broadcast date and time of the advertisement broadcast and the arrival device which is a device expected to transmit the advertisement broadcast on the broadcast date and time. A storage unit that stores ad space data that indicates the arrival device information indicating a set for each ad space, and a set of ad space that includes the broadcast date and time within a predetermined broadcast period based on the ad space data. An analysis in which the total number of reached devices of the ad space included in the above is counted as the total number of reached, without duplication between the ad space, and at least one of the sets satisfying a predetermined application condition is selected based on the total number of reached. It is an information processing device including a unit.

Another aspect of the present invention shows a set of advertising space data stored in advance in the storage unit, which is at least the broadcast date and time of the advertisement broadcast and the arrival device which is the device expected to transmit the advertisement broadcast at the broadcast date and time. Based on the ad space data that shows the arrival device information for each ad space, the total number of the reachable devices of the ad space included in the set is reached for each set of the ad space that includes the broadcast date and time within the predetermined broadcasting period. An information processing method having a first step of counting the number of ad slots without duplication, and a second step of selecting at least one of the sets satisfying a predetermined application condition based on the total number of reached. be.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(System overview)
First, an outline of the information processing system 1 according to the present embodiment will be described.
FIG. 1 is a schematic block diagram showing an example of the functional configuration of the information processing system 1 according to the present embodiment. The information processing system 1 includes an information processing device 10 and a receiving device 20. The information processing device 10 is connected to the receiving device 20 so as to be able to transmit and receive various data by wire or wirelessly using the network NW.

In the example shown in FIG. 1, the number of receiving devices 20 is two, but it may be one or three or more. The plurality of receiving devices 20 are distinguished from 20-1, 20-2, etc. by using child numbers. Further, each component unit (for example, a control unit) of the receiving device 20 is also distinguished by using a child number. In the following description, unless otherwise specified, it is assumed that the functional configurations of the plurality of receiving devices 20 are the same and operate independently of each other.

Based on the advertising space data, the information processing apparatus 10 advertises the total number of reachable devices for each group of advertising space including the broadcast date and time within a predetermined aggregation period as the total number of reached. Calculate without duplication between frames. The advertising space data is configured for each advertising space to include a broadcast date and time and arrival device information indicating a set of arrival devices, for example, receiving devices 20 that are expected to receive advertisement broadcasts at the broadcast date and time. Reaching device means a device that receives an advertisement broadcast, that is, a device transmitted by the advertisement broadcast. Reaching equipment is also referred to as reach equipment or reach terminals. The number of reachable devices that receive each one advertisement broadcast is called the reachable number. For example, even if the same receiving device 20 receives the same advertisement broadcast a plurality of times, the contribution to the number of arrivals by the reception of the receiving device 20 is one. The number of arrivals is an index that quantitatively indicates the size of the range of devices for which advertisement broadcasts are received. The number of arrivals and the total number of arrivals are also called the number of reach or the number of transmissions, and the total number of reach or the total number of transmissions, respectively.

The information processing apparatus 10 counts the total number of reachable devices for each ad space as the total number of arrivals without overlapping between a plurality of ad spaces. Then, the information processing apparatus 10 selects one of the sets of the advertising space satisfying the predetermined constraint condition based on the total number of reached. Although FIG. 1 shows one information processing device 10, the number of information processing devices 10 may be two or more. Further, the individual functions or combinations of functions of the information processing apparatus 10 may be shared among a plurality of devices, and the functions of the information processing apparatus 10 may be realized by a device group including the plurality of devices. In the following description, the case where the information processing device 10 is a single server device is mainly used.

The receiving device 20 receives broadcast content data of broadcast content from a broadcasting station via a broadcast transmission line, and presents one or both of video and audio included in the received broadcast content data. This provides broadcast content. The broadcast transmission line is configured to include a broadcast wave having a predetermined frequency band corresponding to the broadcast channel. The broadcast channel can be selected according to the user's operation. The receiving device 20 specifies the date and time and the broadcasting channel for receiving the broadcasting content data, and generates at least the identification information (device ID) indicating the own device, the date and time for receiving the broadcasting content, and the receiving information including the broadcasting channel. The receiving device 20 directly or indirectly transmits the generated received information to the information processing device 10 via the network NW. The indirect transmission includes, for example, the meaning of transmitting to a received information collection server (described later). The reception information collection server accumulates reception information for each reception device 20, and a reception history (reception log) is formed. The reception information collection server transmits a part or all of the formed reception history to the information processing apparatus 10. The reception history can also be regarded as data indicating the reception status of the broadcast for each receiving device 20.

The receiving device 20 is, for example, a television receiver. However, the receiving device 20 may be an electronic device realized in another form as long as it has a function of receiving broadcast content data via a broadcast transmission line. The receiving device 20 may be, for example, any of a mobile phone (including a so-called smartphone), a tablet terminal device, a personal computer, and the like. However, in the following description, the case where the receiving device 20 is a television receiver and can be a reachable device is mainly used.

Various external devices 40 are connected to the network NW. The external device 40 may include, for example, an advertising space providing server, a content information server, a received information collecting server, and the like. The advertising space providing server provides, for example, the advertising space data of each broadcasting station or broadcasting channel to the information processing apparatus 10. The content information server provides the information processing apparatus 10 with content information data indicating broadcast content that has been broadcast, is being broadcast, or is scheduled to be broadcast for each date and time in each broadcasting station or broadcasting channel. The broadcast content specified by the content information data is not limited to the main program, but also includes advertising broadcasts. The reception information collection server receives reception information from the reception device 20, accumulates the received reception information for each reception device 20, and forms a reception history. The reception information collection server provides the formed reception history to the information processing apparatus 10.

In the present application, the broadcast content refers to the content transmitted by broadcasting, and includes the main program and the commercial. The main program is a program that is the main body of the content transmitted by broadcasting. The main program corresponds to the broadcast program stipulated in the Broadcasting Law. The main program includes broadcast programs such as news programs, educational programs, cultural programs, and entertainment programs. CM is a broadcast content whose main purpose is to advertise products and services that are the target of commercial transactions. CMs are also called advertising broadcasts and are not always included in broadcast programs stipulated in the Broadcasting Law. In many cases, the broadcast time of the CM is set within the broadcast time of the main program as illustrated in FIG. In the following description, the broadcast time of the CM or the broadcast time of the main program including the broadcast time is referred to as an advertising space. The ad space is a nominal time zone presented when recruiting advertisers, and the entire individual time zone is not always occupied by the CM broadcast time (for example, 15 seconds to 1 minute). .. In addition, the advertising space is not set for all the main programs, and there are some main programs in which the advertising space is not set. ○ indicates the existence of the advertising space set for the main program, and unmarked indicates that the advertising space does not exist. The advertising space may be provided in a time zone between the broadcast times of two time-adjacent main programs.

Broadcasters usually recruit advertisers by arbitrarily setting the broadcast date and time of each ad space and the amount of consideration. The advertising space information exemplified in FIG. 5 shows the name of the broadcasting station as a broadcasting company, the broadcasting date and time, the amount of consideration, and the audience rating. The "Y0-M0-D0, h0: m0 to h1: m1" of the advertising space BC01 indicates that the broadcast date and time is the period from h0: m0 to h1: m1 on D0, M0, Y0. In many cases, the higher the expected audience rating, the higher the amount will be set as consideration. The inventory information may indicate a broadcast channel on behalf of or with the broadcaster.

(Information processing device)
Next, an example of the functional configuration of the information processing apparatus 10 will be described. The information processing device 10 includes a communication unit 120, an information storage unit 130, and a control unit 140.
The communication unit 120 enables transmission / reception of various data by wire or wirelessly with other devices via the network NW. The communication unit 120 includes, for example, a communication interface.
The information storage unit 130 stores data indicating various types of information acquired by the control unit 140. The information storage unit 130 stores, for example, advertising space data, content information data, reception history, and the like.

The control unit 140 executes a process for exerting the function of the information processing apparatus 10 and a process for controlling the function. The control unit 140 includes a data input unit 142, an external data acquisition unit 144, an information analysis unit 146, and a data output unit 148.

The data input unit 142 acquires the input data related to the application of the advertising space. The data input unit 142 is generated by using an operation signal input from an operation unit (not shown) provided in the information processing apparatus 10. The data input unit 142 may input input data from another device (for example, an advertiser's terminal device, a broadcaster's terminal device, etc.) connected to the information processing device 10. The data input unit 142 outputs the acquired input data to the information analysis unit 146.

The input data includes at least information indicating the application conditions for the ad space. The ad space application conditions include, for example, one or both of the target total number reached and the budget amount. The target total number of reached is the target value of the total number of reached devices for each selected ad space. The total number of reach of the target is also called the total number of reach of the target. The number of ad slots selected can be 0 or 1, but generally 2 or more. The target total number of achievements is an example of an index that quantitatively indicates the magnitude of the effect expected by the advertiser on the advertisement broadcasting performed by using the selected advertising space. The budget amount means the upper limit of the amount of money that can be spent on the purchase of the selected inventory. The budget amount contributes to the burden on the advertiser for advertising broadcasting. The input data may include a broadcast period for broadcasting an advertisement. Advertising space that includes the broadcast date and time within the broadcast period will be selected.

The external data acquisition unit 144 acquires external data from the external device 40 using the communication unit 120, and stores the acquired external data in the information storage unit 130.
The external data acquisition unit 144 receives new advertising space data from the advertising space providing server, and stores the received advertising space data in the information storage unit 130.

The external data acquisition unit 144 receives the content information data from the content information server every predetermined period (for example, 1 hour to 1 day), and stores the newly received content information data in the information storage unit 130. The external data acquisition unit 144 may receive only the newly accumulated content information data without receiving the content information data acquired in the past from the content information server (difference update). The external data acquisition unit 144 separates the content information data multiplexed into the broadcast content data transmitted from the broadcasting station using the broadcast wave, and stores the newly acquired content information data in the information storage unit 130. You may. In that case, the content information server may be omitted.
The external data acquisition unit 144 receives the reception history of each of the receiving devices 20 from the reception information collection server every predetermined period (for example, 1 hour to 1 day), and the newly received reception history is transmitted to the information storage unit 130. Remember. The external data acquisition unit 144 may receive only the newly accumulated reception history without receiving the reception history acquired in the past from the reception information collection server.

When the input data is input from the data input unit 142, the information analysis unit 146 refers to the advertising space data stored in advance in the information storage unit 130 based on the broadcast period and application conditions indicated by the input data, and the broadcast period. Specify the ad space that includes the broadcast date and time. As illustrated in FIG. 2, the information analysis unit 146 includes an equipment aggregation unit 1462 and a combination analysis unit 1464.

The device totaling unit 1462 uses the reception history stored in the information storage unit 130 to generate arrival device information in advance for each advertising space, and stores the generated arrival device information in the information storage unit 130. The arrival device information is information indicating a set of expected arrival devices, which are devices that are expected to transmit the advertisement broadcast on the broadcast date and time of the advertisement space. The device totaling unit 1462 determines as an expected arrival device a device that has received an advertisement at least once on the same broadcast date and time as the ad space in a predetermined totaling period in the past. An example of a method for determining an expected arrival device will be described later. The device totaling unit 1462 may include the arrival device information indicating the set of the determined predicted arrival devices in the advertisement space data in association with the advertisement space.

The combination analysis unit 1464 determines one or more specified sets of ad slots so as to satisfy the application conditions. The combination analysis unit 1464 outputs the selection information indicating the selected set of advertising space to the data output unit 148. The combination analysis unit 1464 may include information on the selected set of ad slots, the total amount of consideration for the set, and the total number of reached in the set in the selection information.
When two or more ad slots are included in the set of ad slots, the expected reach devices included in the reach device information corresponding to each ad slot overlap between the ad slots, that is, a common expected reach device. May occur. In the example shown in FIG. 6, the advertising space BC01 includes the device D11, the device D12, and the device D13 as the expected arrival device, and the advertising space BC02 includes the device D13, the device D15, and the device D16 as the expected arrival device. Among those expected arrival devices, the device D13 overlaps between the advertising space BC01 and the advertising space BC02. Therefore, the combination analysis unit 1464 counts the total number of expected arrival devices for each advertising space as the total number of arrivals so that the expected arrival devices do not overlap between the advertising spaces.

In the example shown in FIG. 6, for the set of the advertising space BC01 and the advertising space BC02, the expected arrival devices are the device D11, the device D12, the device D13, the device D15, and the device D16. Therefore, the total number of units reached is five. Since the number of arrivals of the advertising space BC01 and the advertising space BC02 is 3 each, the total number of arrivals may be less than the simple total value of 6 units reached for each advertising space. In order to count the total number of arrivals, the combination analysis unit 1464 may count each expected arrival device indicated by the arrival device information for each advertising space only once, or the total number of total arrivals between the advertising spaces. Therefore, for each set of two ad slots, the number of expected arrival devices that overlap between the ad slots belonging to the set may be subtracted.

If the application conditions include the target total number of achievements, the combination analysis unit 1464 determines a set of advertising space in which the total number of achievements is equal to or greater than the target total number of achievements.
If the application conditions include the budget amount, the combination analysis unit 1464 calculates the total amount of consideration for each of the ad slots included in the set set of ad slots. Then, the combination analysis unit 1464 determines a set of advertising space in which the calculated total amount is equal to or less than the budget amount.
If the application conditions include both the total target number and the budget amount, the Information Analysis Department 146 will create a set of advertising space in which the total number of achievements is equal to or greater than the target total number reached and the total amount is less than or equal to the budget amount. stipulate.

When the number of sets determined by using any of these application conditions is two or more, the combination analysis unit 1464 may select one set of the ad space with the largest total number of reached. , One set of the advertising space with the smallest total amount may be selected, or one set of the advertising space with the smallest number of advertising space included in the advertising space group may be selected. Further, the combination analysis unit 1464 is not limited to the set of one selected ad space, and the data output unit 148 receives selection information related to each of the two sets corresponding to all or part of the set satisfying the application condition. You may output it.

If there is no set of ad space whose total number of arrivals is equal to or greater than the target total number of arrivals, the combination analysis unit 1464 may select the set of ad space with the maximum total number of arrivals, or the total number of arrivals. You may select a predetermined number of ad space sets in descending order of.
If there is no set of ad slots whose total consideration is less than or equal to the budget amount, the combination analysis unit 1464 may select the set of ad slots with the lowest total consideration, or in ascending order of the total consideration. A predetermined number of inventory sets may be selected.
If the total number of reached is equal to or greater than the target total number of reached and there is no set of ad slots whose total amount is less than or equal to the budget amount, the combination analysis unit 1464 may select the set of ad slots with the smallest total amount. Alternatively, the set of ad slots with the highest total target number may be selected. In that case, the combination analysis unit 1464 may select a predetermined number of ad space sets in ascending order of the total amount of consideration, or select a predetermined number of ad space sets in descending order of the total number of reached. You may.
Although the set of ad slots selected in this way does not satisfy the application conditions, the combination analysis unit 1464 may output selection information related to each set of selected ad slots to the data output unit 148.

Returning to FIG. 1, the data output unit 148 generates output data indicating selection information input from the information analysis unit 146. As mentioned above, the selection information may include a set of ad slots, as well as one or both of the total consideration for each set and the total number of arrivals in that set. The data output unit 148 may output the generated output data to a display unit wirelessly or wiredly connected to the own device, or may be used by another device (for example, an advertiser's terminal device) via the communication unit 120. May be sent to.

The interface unit 118 corresponds to the communication unit 120 described above.

(Receiver)
Returning to FIG. 1, an example of a functional configuration of the receiving device 20 according to the present embodiment will be described.
The receiving device 20 includes a communication unit 210, a broadcast receiving unit 220, an operation information acquisition unit 230, a control unit 240, and an information presenting unit 250.
The communication unit 210 connects to other devices via the network NW so that various data can be transmitted / received wirelessly or by wire. The communication unit 210 is configured to include, for example, a communication interface.

The broadcast receiving unit 220 receives a received signal based on a broadcast wave having a predetermined frequency band corresponding to the broadcast channel indicated by the channel information input from the control unit 240, and receives the received signal as a base band reception signal. Convert to. The broadcast receiving unit 220 converts the converted received signal into broadcast data by demodulating it using a predetermined demodulation method. The broadcast receiving unit 220 extracts video data and audio data from the converted broadcast data, and outputs the extracted video data and audio data to the information presenting unit 250. Video data and audio data are components that make up broadcast content data.

The operation information acquisition unit 230 accepts the user's operation and generates operation information indicating various commands instructed by the accepted operation. The operation information acquisition unit 230 outputs the generated operation information to the control unit 240. The operation information acquisition unit 230 may be provided with a dedicated member such as a button, a lever, or a dial, or may be provided with a general-purpose member such as a mouse, a touch pad, or a touch sensor. The operation information acquisition unit 230 may include a receiver that receives operation information from another device, for example, a remote control device (remote controller), a mobile phone, or the like. The operation information may indicate the start (ON) or stop (OFF) of the operation, the broadcast channel (CH) for receiving, and the like.

The control unit 240 controls various processes for exerting the functions of the receiving device 20 and those processes. The control unit 240 realizes a function instructed by the operation information input from the operation information acquisition unit 230. The control unit 240 is configured to include any one of a processor such as a CPU, an arithmetic circuit for performing various arithmetic processing, or a combination thereof. The processor may be configured as a computer that executes a predetermined program and realizes a function as a control unit 240.

For example, when the operation information indicating the start of operation is input from the operation information acquisition unit 230, the control unit 240 outputs an operation start signal indicating the start of operation to each unit of the receiving device 20 to start the operation of each unit. At this time, each part reads out (initializes) the operation parameters saved in advance, and starts the operation using the read operation parameters. The control unit 240 outputs channel information indicating a predetermined broadcast channel or a broadcast channel when the operation is finally completed to the broadcast receiving unit 220. As a result, reception of the broadcast program on the broadcast channel indicated by the channel information is started. On the other hand, the control unit 240 generates reception information including the identification information (device ID) indicating the own device, the date and time at that time, and the reception channel indicating the broadcast channel, and the generated reception information is sent to the reception information collection server. Transmission is performed using the communication unit 120.

When the operation information indicating the broadcast channel is input from the operation information acquisition unit 230, the control unit 240 outputs the channel information indicating the broadcast channel indicated by the operation information to the broadcast reception unit 220. As a result, reception of the broadcast program on the broadcast channel switched by the user's operation is started.
When the operation information indicating the operation stop is input from the operation information acquisition unit 230, the control unit 240 outputs an operation stop signal indicating the operation stop to each unit and stops the operation of each unit. At this time, each part saves the operation parameter at that time, and then stops the operation. The control unit 240 stores channel information indicating the broadcast channel finally instructed to the broadcast reception unit 220. Further, the control unit 240 generates reception information including the identification information indicating the own device, the date and time at that time, and the operation stop information indicating the operation stop, and sends the generated reception information to the reception information collection server in the communication unit 120. Send using. After that, the control unit 240 stops the power supply to the own device. However, the control unit 240 consumes electric power for maintaining the minimum function. The minimum function includes, for example, electric power for receiving operation information indicating the start of operation and enabling the start of operation of the own device.

When the operation information acquisition unit 230 includes a touch sensor, the touch sensor and the display may be integrated and configured as a touch panel.

(Data structure)
Next, a data configuration example of various data according to the present embodiment will be described. 7 and 8 show examples of input data indicating application conditions for advertising space, respectively. FIG. 7 shows that the “broadcast period” of the advertising space pertaining to the application is the period from August 8, 2020 to August 21, 2020. Further, FIG. 7 shows that the “total target number reached” of the advertising space related to the application is “200,000 units”. FIG. 8 also shows that the “broadcast period” of the advertising space related to the application is the period from August 8, 2020 to August 21, 2020. FIG. 8 shows that the “budget amount” of the advertising space related to the application is “1 million yen”.

9 and 10 show examples of output data indicating the selected advertising space, respectively. The output data shown in FIGS. 9 and 10 indicate the advertising space selected based on the input data shown in FIGS. 7 and 8, respectively. For example, FIG. 9 shows that the "combination of selected advertising space" is a set consisting of the advertising space "BC01" and "BC02", and the "total amount" of the consideration is "1 million yen" and "total". It shows that "the number of arrivals" is "210,000 units". This "total amount" is the sum of the consideration for each of the advertising space "BC01" and "BC02". This "total number of arrivals" is the total number of devices that are counted without duplication for the entire set of receiving devices 20 that are the expected arrival devices of the advertising space "BC01" and "BC02", and is the "total number of arrivals of the target". More than 200,000 units of "number".
FIG. 10 shows that the "combination of selected ad slots" is a set consisting of ad slots "BC01" and "BC04", the "total amount" is "900,000 yen", and the "total number reached" is. Indicates that it is "200,000 units". This "total amount" is the total of the consideration for each of the advertising space "BC01" and "BC04", and is less than the "budget amount" of "1 million yen". The "total number of arrivals" is the total number of devices that are counted without duplication for the entire set of receiving devices 20 that are the expected arrival devices of the advertising space "BC01" and "BC04".

FIG. 11 is a diagram showing an example of advertising space data. The inventory data indicates at least the broadcast date and time for each inventory. In the example shown in FIG. 11, the broadcast date and time is represented by a set of "broadcast date", "start time", and "end time". For example, the broadcast date and time of the advertising space "BC01" is between 5 am and 6 am on September 1, 2020. As illustrated in FIG. 11, the advertising space data may include information on an "amount" as a consideration for the advertising space and may be associated with the advertising space. For example, the consideration for the advertising space "BC01" is 200,000 yen. However, in the example shown in FIG. 11, the arrival device information is not included in the advertising space data.

FIG. 12 is a diagram showing an example of arrival device information. The arrival device information indicates a set of expected arrival devices for each advertising space. The expected arrival device is a device that is expected to transmit the advertisement broadcast at the broadcast date and time of the advertisement space, for example, the receiving device 20. In the example shown in FIG. 12, the expected arrival devices are devices D01, D03, D07, ..., Dn01. In this example, the reachable device information is configured separately from the inventory data.

FIG. 13 is a diagram showing an example of reception history. The reception history is formed by accumulating individual reception information. In the example shown in FIG. 13, the individual received information includes the log ID, the device ID, the date and time, and the channel information. The log ID is identification information for identifying individual received information. The log ID is uniquely defined and assigned to each received information in the received information collection server. However, the log ID does not necessarily have to be included in the received information. The device ID is identification information indicating a device that has received a broadcast program, for example, a receiving device 20. The date and time indicate the time when reception on the corresponding broadcast channel started. The channel information indicates the broadcast channel that received the broadcast content. Therefore, in the reception history, the device indicated by the identification information included in the received information of interest during the period from the date and time indicated by a certain received information to the date and time indicated by the received information arranged immediately after that. Indicates that broadcast content is received on that broadcast channel. In the example shown in the second and third rows of FIG. 13, the device D01 is on the broadcast channel 10 in the time zone from 18:32:20 on August 10, 2020 to 18:44:30 on the same day. Indicates that the broadcast content to be broadcast is received. This time zone may include one or both of the broadcast time of the main program and the broadcast time of the commercial. Note that the reception channel item may include reception stop information.
Therefore, the device aggregation unit 1462 sets the period from the date and time indicated by the reception information to the date and time indicated by the next reception information for the reception channel indicated by a certain reception information for the device specified by the device ID. It can be specified as one reception period.

FIG. 14 is a diagram showing an example of content information data. The content information data includes a content ID, a broadcast channel, a broadcast date, a start time, and a broadcast time (duration) for each broadcast content, and is configured by associating them with each other. The end time is the time when the broadcast time has elapsed from the start time. The broadcast date, start time, and broadcast time are information indicating the broadcast date and time. In the example shown in FIG. 14, PM01 in the second line and PM02 in the fourth line are content IDs indicating the main program. CM01 in the third row, CM02a in the fifth row, and CM02b in the sixth row are content IDs indicating advertisement broadcasting, respectively. The content information data may be independently produced and provided by the broadcaster, may be data created by recording the broadcast result after broadcasting, or may be multiplexed with the broadcast content data and transmitted by broadcast waves. It may be a part of system information (for example, an event information table).

Next, the device aggregation unit 1462 will explain a method of identifying the predicted arrival device using the content information data.
The device aggregation unit 1462 includes the broadcast date and time of the advertisement broadcast shown in the content information data in a predetermined aggregation period set in advance, and the broadcast date and time of the advertisement space (hereinafter referred to as the target advertisement space) to be processed. Identify advertising broadcasts that are included in the same time zone. The aggregation period should be long enough to ensure the reliability of the number of arrivals for each ad space, for example, one month before the month to which the point belongs, or one to three months before that point. It can be arbitrarily set as long as it has a period in which the preference of each user does not change significantly until the broadcasting period.

The device totaling unit 1462 may specify the advertisement broadcast by substituting the condition that the time zone is the same as the target advertisement space, or by imposing the condition and the condition that the broadcast date is the same broadcast date type as the target advertisement space. .. For example, the day of the week may be applied as the broadcast date type. As the broadcast day type, the distinction between weekdays and holidays or Saturdays and holidays may be applied instead of the day of the week. As described above, as the broadcast day type, the type of the day in which a significant difference in the reception time of the broadcast according to the life pattern of each user is recognized may be applied. Therefore, it can be estimated that there is a high possibility that the advertisement broadcast will be received at the broadcast date and time of the same broadcast date type as the date and time when the advertisement broadcast was received in the past. Therefore, the device aggregation unit 1462 considers a device having a target advertising space having the same broadcast date type as the specified advertisement broadcast and having the same time zone as the broadcast date and time to be a reachable device. Can be estimated.

Therefore, the device totaling unit 1462 counts for each device the number of times the reception period specified based on the reception history includes the specified advertisement broadcast as the number of receptions. The device totaling unit 1462 defines a device whose number of receptions is equal to or greater than a preset determination threshold value of the number of receptions as an expected arrival device. The determination threshold is an integer value of 1 or more, for example, 3 to 5. However, the device totaling unit 1462 may calculate the ratio of the broadcast time of the advertisement broadcast to the total broadcast time of the advertisement broadcast included in the reception period specified based on the reception history. The device totaling unit 1462 includes the case where the calculated ratio is equal to or more than the predetermined determination ratio (for example, 50 to 90%) in the number of receptions, and does not include the case where the calculated ratio is less than the determination ratio in the number of receptions. You may. This is because if the reception period is short, the user of the device may have low interest in the advertisement broadcast or may have a feeling of refusal.

The device totaling unit 1462 may determine the attribute of the user corresponding to the receiving device 20 by referring to the user data stored in the information storage unit 130 in advance for the predetermined advertising space. The device totaling unit 1462 may set the determination threshold value based on the determined user attribute. When the determined user attribute is a specific user attribute, the device aggregation unit 1462 may set a determination threshold value smaller than that of other user attributes. For example, if the determined user attribute is a woman in her 20s or 30s, the determination threshold is set to 2 times, and if the determined user attribute is another user attribute, the determination threshold is set to 3 times. good. As a result, reception by a listener having a specific user attribute can be detected without omission. The ad space data may include information on a specific user attribute of the ad space, or a determination threshold value for each specific user attribute may be set. The device totaling unit 1462 determines whether or not the advertising space data includes information on these user attributes and information on the determination threshold value, and if so, determines that information is the predicted arrival device. Applies to.

Next, an example of user data will be described. The user data exemplified in FIG. 15 includes a user ID for each device ID of the receiving device 20, a gender as an example of user attributes, and a date of birth, and includes these in association with each other. The gender and age based on the date of birth corresponding to the device ID included in this user data are specified. As an example, the user data may further include a linked device ID for each device ID of the receiving device 20 and may be associated with the user data. As the linked device ID, an electronic device used by the user of the receiving device 20 may be set as the linked device, for example, a device ID such as a mobile phone, a tablet terminal device, a personal computer, or a recording device. These electronic devices may also have the ability to receive broadcast programs. Therefore, the information processing device 10 can acquire the reception history of the cooperation device separate from the reception device 20 as well as the reception device 20 as the representative device for each user, and the cooperation device is based on the acquired reception history. It is possible to analyze the reception status of broadcast contents. The user attribute and the linked device ID, which are elements of the user data, are set, for example, based on the operation information for the receiving device 20 or the linked device at the start of use of the receiving device 20 or at an arbitrary time point, and the information storage unit 130 receives. It can be acquired directly or indirectly from the device 20 or the linked device via the network NW.

The reception information collection server may also accumulate reception information for each of the linked devices, collect it as a reception history, and provide it to the information processing device 10. Then, the device totaling unit 1462 counts the number of receptions for the target advertising space for the reception history of the linked device as well as the reception device 20, and obtains the counted number of receptions by adding the number of receptions to the reception device 20. Based on whether or not the total number of received receptions is equal to or greater than the determination threshold value, it may be determined whether or not the receiving device 20 which is the representative device of the cooperation source is the expected arrival device. As a result, it is determined whether or not the reception by the cooperating device is also the expected arrival device as a part of the reception by the user of the receiving device 20. Therefore, it is possible to avoid duplication of counting for the number of arrivals between the cooperative device and the receiving device 20, and to more accurately estimate the range of users who are expected to reach the advertisement broadcast. The number of linked devices that can be registered is not limited to one for each user, and may be a plurality of devices. The expected arrival device is not necessarily limited to the receiving device 20, and may be any one of the representative device and one or more linked devices for each user. Even in that case, it is possible to avoid duplication of counting with respect to the number of arrivals.

FIG. 16 is a diagram showing another example of advertising space data. The advertising space data shown in FIG. 16 is configured to include the arrival device information shown in FIG. 12 for each advertising space in the advertising space data shown in FIG. 11. That is, the advertising space data shown in FIG. 16 is configured to include the broadcast date and time, the amount of money (compensation), and the arrival device information indicating the expected arrival device for each advertisement space. The advertising space data shown in FIG. 16 is stored in the advertising space "BC01" on September 1, 2020, with a broadcast date of September 1, 2020, a start time of 5 am, an end time of 6 am, an amount of 200,000 yen, and a device D01 as a set of expected arrival devices. , D03, D07, ..., Dn01 are associated with each other.

Although the input data shown in FIGS. 7 and 8 includes information on the broadcasting period as an example, the present invention is not limited to this. The input data does not have to include information on the broadcast period. In that case, the broadcast period information may be set in advance in the combination analysis unit 1464.

In the above description, the combination analysis unit 1464 mainly searches for a combination of ad space that satisfies the application conditions, but the present invention is not limited to this. A full search corresponds to a so-called exhaustive search. The combination analysis unit 1464 may apply other methods of combinatorial optimization. The combination analysis unit 1464 can, for example, apply the knapsack problem to search for a combination of advertising space that satisfies the application conditions.

The knapsack problem is when one knapsack with a capacity W and items of type I (I is an integer of 1 or more) are given, and when one or more items are packed in the knapsack within the range not exceeding the capacity W. , Is the problem of finding the combination of items to choose in order to maximize the sum of the values of the items in the knapsack. This problem can also be regarded as an integer programming problem for finding one or more sets of goods i that maximize the numerical value shown in the first row under the conditions shown in the second row of the equation (1). ..

In the formula (1), i is an index indicating the type of the item and is represented by an integer between 1 and I. v _i and wi are real numbers indicating the value and volume of the item _i , respectively. However, it is assumed that only one item i is selected for each item i. _xi is an integer indicating whether or not the item i is selected. x _i = 1 indicates that the item i is selected, and x _i = 0 indicates that the item i is not selected. The problem with such restrictions is called the 0-1 knapsack problem.
The 0-1 knapsack problem involves trying two options, selecting or not selecting an item, for all combinations of the number of items (full search). Since the amount of calculation is proportional to ^2I , the amount of calculation increases sharply as the number of types of goods increases.

As another method, a greedy algorithm solution can be selected, but when the greedy algorithm is adopted, the optimum solution is not always calculated. However, the combination analysis unit 1464 applies the following solution method (dynamic programming, hereinafter, this solution method) to improve the efficiency of solving the 0-1 knapsack problem as compared with the full search. The optimum solution can be obtained. In this solution method, the combination of goods can be determined by using the recurrence formula represented by the formula (2). Since the calculation amount is proportional to the number of items and the number of volume patterns, it is possible to avoid a sudden increase in the calculation amount with respect to the number of product types I.

In the formula (2), V (i, w) is loaded into the knapsack from the item 1 to the item i, and the loaded item when the capacity for further loading the item (hereinafter, the loadable capacity) is w. Shows the total value of. MAX (..., ...) Indicates that the larger value of ... and ... is adopted. The first row on the right side of the equation (2) shows the total number of selected items because there are no items that can be loaded when there are no items that can be selected (i = 0) or when the loadable capacity w is 0. Indicates that the value is 0. The second line on the right side of the equation (2) is loaded from the item 1 to the item i-1 without adding the item i because the capacity w _i of the item i exceeds the loadable capacity w. It is shown that the total value V (i-1, w) of the goods is defined as the total value V (i, w). At this time, the loaded items 1 to i-1 are selected. In other cases, the third line on the right side of the equation (2) is the total value V (i, w) from the loaded item 1 to the item i, and the total value V (i) from the item 1 to the item i-1. It is shown that the value obtained by adding the value vi of the item _i to -1, w-w _i ) is compared with the total value V (i-1, w) to calculate the one having the maximum total value. This indicates that if the loadable capacity w can be secured even if the item i is packed, the load is loaded if the value can be maximized by further packing the item i, and the load is not performed if the value cannot be maximized.

This solution method has the following steps. In this solution method, the combination analysis unit 1464 determines the capacity of the knapsack for each of the number of items i + 1 (for example, 0, 1, 2, ... N; N is a predetermined integer indicating the number of items). A sequence of numbers (for example, 0, 10) containing M + 1 (number of elements) as an element value that is an integral multiple of the unit capacity (resolution) divided into M equal parts (M is a predetermined integer indicating the number of divisions of the capacity). , 20, ..., Capacities of knapsacks) in a two-dimensional array of (N + 1) rows (M + 1) columns, the total value V (i, w) obtained by performing the calculation described below, and the packed goods. The sequence List [i, w] of is recorded in association with the values of the item i and the loadable capacity w. In this solution method, when considering the value obtained by the previous calculation in the process of performing the iterative calculation, the combination analysis unit 1464 refers to the value and the sequence stored in the above-mentioned sequence. (Step S02) When i = 0 in the first row on the right side of the equation (2), the combination analysis unit 1464 sets the total value V (i, w) to 0 in all w. (Step S04) When i> 0, the combination analysis unit 1464 determines whether or not the capacity of the product exceeds w for all the values of w in the product i. (Step S06) When the loadable capacity w is exceeded, the combination analysis unit 1464 determines that the item i cannot be loaded, and from the item 1 to the item i-1 according to the second row on the right side of the equation (2). The total value V (i-1, w) of the goods loaded in is defined as the total value V (i, w), and List [i-1, w] is set as an array of goods packed with List [i, w]. Record. (Step S08) When the combination analysis unit 1464 does not exceed the loadable capacity w, the combination analysis unit 1464 uses the third row on the right side of the equation (3) to set the total value V (i-1, ww _i ) to the product. When the value obtained by adding the value v _i of i and the total value V (i-1, w) are compared, the one with the maximum total value is defined as the total value V (i, w), and the item i is added. Adds the item i to List [i-1, w-w _i ] and saves it as List [i, w]. If the item i is not added, the item is packed with List [i-1, w]. The sequence of List [i, w] is saved. (Step S10) The combination analysis unit 1464 adds 1 to the current i (increment), and returns to the process of step S04. As a result, the total value V (N + 1, M + 1) is given as the optimum solution in the obtained two-dimensional array, and the array List (N + 1, M + 1) of the products packed at that time is the combination of the products that is the optimum solution. Further, the set of i and w having the same total value as the total value V (N + 1, M + 1) related to this optimum solution is also a combination that becomes a separate optimum solution. In the above description, the case where the combination of goods is recorded as List [i, w] is illustrated, but it is also possible to back-calculate the combination of goods from the finally obtained sequence. Therefore, it is not essential to have List [i, w] record the combination of items.

In the present embodiment, the combination analysis unit 1464 can apply the knapsack problem in the selection of the advertising space including the budget amount as an application condition. Here, the combination analysis unit 1464 applies the advertising space _i , the consideration wi, the received number _vi , instead of the item, the volume of each item, and the value, respectively, and applies the capacity of the knapsack, the total value of the loaded item, and so on. Instead of the maximum capacity, the budget amount W, the total number of received numbers V (i, w), and the surplus amount w are applied, respectively. The surplus amount w is an amount obtained by subtracting the total amount of consideration for the already selected advertising space from the budget amount W. In other words, the surplus amount w is an amount that can be used to acquire further advertising space i by the time the budget amount W is reached.

However, in the present embodiment, instead of the third line of the formula (2), as shown in the third line of the formula (3), the combination analysis unit 1464 is the total from the ad space 1 to the ad space i-1. The number of arrivals v _i of the ad space i is added to the number of arrivals V (i-1, w-w _i ), and the expected arrival devices up to the ad space i-1 in the set e _i of the expected arrival devices of the ad space i The total number of devices V (i, w) reached to the ad space i is determined by subtracting the number O (ei, E _{i -1} ) of the devices overlapping with the entire set E _i-1 .

As a result, it is possible to avoid a sudden increase in the amount of calculation due to an increase in the number of advertising spaces, so that it is possible to efficiently determine the combination of advertising spaces. In the example shown in FIG. 17, the amount of calculation is calculated when the budget amount is 1 million yen, the step size (resolution) of the budget amount is 100,000 yen, and the number of advertising slots in the broadcast period to be selected is 1 to 13. An example is shown. In the full search, the amount of calculation increases sharply as the number of ad slots increases, but in this solution, the amount of calculation is proportional to the number of ad slots. When the number of ad slots is 10, the calculation amount of both is almost the same, but when the number of ad slots during the broadcast period increases, the calculation amount of this solution method is overwhelmingly larger than that of the full search. Less.

Next, an example of selecting an ad space combination that applies the knapsack problem will be described.
FIG. 18 is a list showing still other examples of output data. FIG. 18 shows the combination of the total number of reached and the advertising space for each budget amount. However, an example is the case where the broadcasting period from September 1, 2020 to September 7, 2020 is set in advance in the combination analysis unit 1464, and the input data includes the budget amount as a recruitment requirement. Further, it is assumed that the combination analysis unit 1464 selects the combination of the advertising space with the largest total number of received advertisements from the advertising space shown in the advertising space data shown in FIG. 16 with the total consideration within the budget amount. ..

If the budget amount is 100,000 yen, the ad space is not selected. This is because the consideration for each ad space exceeds the budget amount. If the budget amount is 200,000 yen to 300,000 yen, one advertising space BC01 is selected, and the total number of units reached is 500,000. If the budget amount is 400,000 yen to 500,000 yen, one advertising space BC05 is selected, and the total number of units reached is 600,000. If the budget amount is 600,000 yen to 700,000 yen, two advertising spaces BC01 and BC05 will be selected, and the total number of units reached will be 1.1 million. If the budget amount is 800,000 yen to 1 million yen, three advertising spaces BC01, BC02, and BC05 will be selected, and each will be 1.2 million units.

In the above description, the case where the combination analysis unit 1464 selects the advertising space (online processing) in response to the input of the input data is taken as an example, but the present invention is not limited to this. The combination analysis unit 1464 selects in advance a combination of advertising space for each set of broadcasting period and application conditions (hereinafter referred to as application set), includes selection information related to the combination of the application set and the selected advertising space, and responds to them. The attached advertising space selection data (not shown) may be stored in the information storage unit 130 (offline processing). The combination analysis unit 1464 may include one or both of the total amount of consideration calculated by the above method and the total number of received information in the information of the combination of the advertising space in the advertising space selection data. Then, the combination analysis unit 1464 receives input data from the network NW, the communication unit 120, and the data input unit 142 from the applicant's device (hereinafter referred to as the applicant's device). The combination analysis unit 1464 extracts selection information indicating information on the combination of the ad space corresponding to the application set that matches the combination of the broadcast period and the application condition indicated by the input data from the ad space selection data. The combination analysis unit 1464 may transmit the output data indicating the extracted selection information to the applicant device as a response to the input data via the data output unit 148.

Further, the combination analysis unit 1464 may generate application screen data indicating one or more application sets in advance, and transmit the application screen data to the applicant device via the communication unit 120 and the network NW. The applicant device can display an application screen based on the application screen data received from the information processing device 10, and depending on the operation of the applicant, one of the application sets displayed on the application screen can be displayed. Make it selectable. When the combination analysis unit 1464 receives the operation information indicating the application set from the applicant device via the network NW, the combination analysis unit 1464 specifies the application set indicated by the received operation information. Then, the combination analysis unit 1464 refers to the advertisement space selection data, extracts the selection information corresponding to the specified application set, and generates output data indicating the extracted selection information. The combination analysis unit 1464 may transmit the output data generated via the data output unit 148 and the network NW to the applicant device. The applicant device can acquire or present information on the combination of advertising spaces indicated by the output data received from the information processing device 10.

(Advertising space selection process)
Next, an example of the advertising space selection process according to the present embodiment will be described. FIG. 19 is a flowchart showing an example of the advertising space selection process according to the present embodiment.
(Step S102) The data input unit 142 acquires input data indicating the broadcast period and the application conditions for the advertising space. The application conditions include information on one or both of the total number of goals reached and the budget amount. After that, the process proceeds to step S104.
(Step S104) The combination analysis unit 1464 does not cause duplication of expected arrival devices between the ad slots for each combination of ad slots including one or more ad slots that include the broadcast date and time within the broadcast period indicated by the input data. The total number of arrivals is counted and the total amount of consideration is calculated. After that, the process proceeds to step S106.
(Step S106) The combination analysis unit 1464 specifies a combination of advertising space that satisfies the application conditions indicated by the input data. After that, the process proceeds to step S108.
(Step S108) When the number of combinations of the specified advertising space is one, the combination analysis unit 1464 generates output data indicating the combination of the advertising space. When the number of specified ad space combinations is two or more, the combination analysis unit 1464 selects any one of the two or more ad space combinations. The combination of ad slots selected may be the one with the highest total number of reached, the one with the lowest total consideration, or the one with the lowest number of ad slots. The combination analysis unit 1464 generates output data indicating selection information related to the combination of the selected advertising space, and outputs the generated output data via the data output unit 148. After that, the process shown in FIG. 19 is terminated.

(Expected arrival device aggregation processing)
Next, an example of the expected arrival device aggregation processing according to the present embodiment will be described. FIG. 20 is a flowchart showing an example of the expected arrival device aggregation process according to the present embodiment.
(Step S202) The external data acquisition unit 144 receives the reception history for each receiving device 20 from the reception information collection server, and stores the received reception history in the information storage unit 130. The external data acquisition unit 144 receives the advertising space data from the advertising space providing server, and stores the received advertising space data in the information storage unit 130. The external data acquisition unit 144 receives the content information data from the content information server, and stores the received content information data in the information storage unit 130. After that, the process proceeds to step S204.

(Step S204) The device aggregation unit 1462 refers to the content information data and broadcasts on the same broadcast time zone as the advertising space to be processed and the same broadcast date type in the predetermined aggregation period. Identify the ad broadcast that was made. After that, the process proceeds to step S206.
(Step S206) The device totaling unit 1462 counts the number of times that the reception period of the broadcast program specified from the reception history of each receiving device 20 includes the broadcast date and time of the specified advertisement broadcast. The device totaling unit 1462 identifies a device whose counted number of times is equal to or higher than a predetermined determination threshold value as a predicted arrival device. After that, the process proceeds to step S208.
(Step S208) The device aggregation unit 1462 stores the arrival device information indicating the specified expected arrival device in the information storage unit 130 in association with the advertising space of interest. After that, the process of FIG. 20 is terminated.

In the above description, the reception history is mainly a real-time (real-time) viewing log for a so-called broadcasting service. The received information included in the real-time viewing log is information (real-time viewing information) indicating the reception status of the broadcast content presented by the receiving device 20 or other devices (hereinafter collectively referred to as a receiving device and the like). However, the reception history may be a so-called recording log or a reproduction log for a broadcasting service. The reception information included in the recording log is information (recording information) indicating the reception status of the broadcast content recorded by the receiving device or the like having a recording function. The received information included in the reproduction log is information (reproduction information) indicating the reproduction (presentation) status of the broadcast content recorded in the past by the receiving device or the like. The reception history is not limited to any one of real-time viewing information, recording information, and playback information, and may include reception information of some or all of these types.
